[Routine help] Okay ladies and gents… HOW are we removing the hair on the back of our thighs?

I literally cannot stand it. I’ve been shaving for like 15+ years and I have never gotten the back of my thighs right. It doesn’t matter which direction I shave, there’s always stubble. And there’s ALWAYS bumps. And I almost always knick my knee ditch. I’ve tried all the creams, the lotions, the shaving gels, many different razors, electric razors, exfoliators, all the “guaranteed” things. The only thing I have yet to try is waxing but I really haven’t the proper money for that yet :( I just need advice because I’m at my wits end with the back of my thighs lol!
